4 GET IN THE KNOW ABOUT SPF50+
ONE It doesn’t provide twice as much protection as
an SPF30+. The two actually deliver very similar protection against UVB rays, the variety that’s the main cause of skin damage and skin cancer.
TWO You need to apply it properly to get that level
of protection. Use one teaspoon of sunscreen per body part, apply it at least 20 minutes before you head outside and then reapply every two hours. THREE You should choose a water-resistant one. Yes, that’s even if you’re not going swimming. Sweating can reduce the effectiveness of nonwater-resistant sunscreen, regardless of the SPF.
